The invention discloses a heterogeneous
energy storage cooperative climbing auxiliary service and
electric energy combined clearing optimization method and
system, and belongs to the field of
electric power system operation and
electric power markets. Aiming at the defects of homogeneous modeling, extensive climbing evaluation and the like in the prior art, an energy
power station and a matched
energy storage aggregation joint unit are innovated for the first time, a three-layer hierarchical collaborative response logic is constructed with a thermal power
generating unit and independent
energy storage, and a climbing demand is accurately matched according to differential
response delay and function positioning. And constructing an integrated joint clearing model containing the
system-level constraint and the main body exclusive refined climbing constraint, taking the minimum total cost of the whole period of the system as a target, solving by adopting a mixed integer
linear programming algorithm, and outputting the clearing electric quantity, the climbing capacity and the price of each main body. According to the method, an independent climbing service market mechanism is set, the climbing
capacity value is dominated, heterogeneous energy storage accurate cooperative compensation is achieved, the rapid climbing requirement of a high-proportion
new energy system can be economically met, and the system
operation safety and the
new energy consumption level are improved.
